The problems involved in estimating real output that I discuss in this paper cause the official government statistics to underestimate of the rates of growth of real GDP, real personal income, and productivity. That underestimation is important not just to economists trying to understand where...

This paper constructs updated measures of productive highway capital stocks at the total, Interstate, Non-interstate, and Local System levels to estimate the contribution of all highways (all public roads) to GDP growth. It presents three types of contribution to GDP growth estimates and an...

This paper re-examines the relationship between population aging and economic growth. We confirm previous research such as Cutler, Poterba, Sheiner, and Summers (1990) and Acemoglu and Restrepo (2017) that show positive correlation between measures of population aging and per-capita output...

We construct an endogenous growth model that includes a cultural variable along the dimension of individualism-collectivism. The model predicts that more individualism leads to more innovation because of the social rewards associated with innovation in an individualist culture. This cultural...

Any economic analysis of climate change policy requires some model that describes the impact of warming on future GDP and consumption. Most integrated assessment models (IAMs) relate temperature to the level of real GDP and consumption, but there are theoretical and empirical reasons to expect...

An increase in the household debt to GDP ratio in the medium run predicts lower subsequent GDP growth, higher unemployment, and negative growth forecasting errors in a panel of 30 countries from 1960 to 2012. Consistent with the “credit supply hypothesis,” we show that low mortgage spreads...

We review the evidence on the practice and effects of discretionary fiscal policy, particularly in the context of recent efforts to stimulate the economy, reaching two main conclusions. First, policy interventions have increased in this decade, pre-dating the 2009 stimulus. Second, despite a...

GDP growth is often measured poorly for countries and rarely measured at all for cities or subnational regions. We propose a readily available proxy: satellite data on lights at night. We develop a statistical framework that uses lights growth to augment existing income growth measures, under...

Incomes per capita have grown dramatically over the past two centuries, but the increase has been unevenly spread across time and across the world. Growth accounting is the principal quantitative tool for understanding this phenomenon, and for assessing the prospects for further increases in...
